6 - 31Chapter 6 Principle of Operation6.3 Fuser Control6.3.1 Fuser ControlThe Halogen Lamp is controllably turned ON and OFF, based on the Fuser control temperature.At the start of warm-up and when the MAIN MOTOR is at rest, the standby temperature is taken asthe Fuser control temperature. When the MAIN MOTOR is operating except at warm-up, the runningtemperature is taken as the Fuser control temperature.6.3.2 ON/OFF Control of Halogen LampThe Halogen Lamp is controllably turned ON and OFF to maintain the Fuser control temperature.6.3.3 Warm-up of FuserThe Halogen Lamp is lit up (turned ON) simultaneously with the start of warm-up of the Fuser. Whenthe temperature of the HEAT ROLL surface (detected temperature of THERMISTER) reaches theFuser control temperature (standby temperature), the warm-up of the Fuser is ended.During warm-up of the Fuser, the MAIN MOTOR is in operation.6.3.4 Fuser Temperature in Ready State180 to 185°C in Ready (standby) state (During operation, it is higher than 185°C.)6.3.5 Fuser Temperature when Abnormal Temperature (higher or lower) is DetectedHigher temperature: 250°CLower temperature: 130°C
